Reproducibility Variable Result LLM Response
Research Type Experimental We study opvi with the Langevin-Stein objective on a mixture model and a generative model of images. 4 Empirical Study We evaluate operator variational inference on a mixture of Gaussians, comparing different choices in the objective. We then study logistic factor analysis for images. 4.1 Mixture of Gaussians 4.2 Logistic Factor Analysis ... Table 1: Benchmarks on logistic factor analysis for binarized MNIST.

Pseudocode Yes Algorithm 1: Operator variational inference
Open Source Code No The paper does not provide any explicit statements about releasing source code or links to a code repository.
Open Datasets Yes We apply logistic factor analysis to analyze the binarized MNIST data set [24]
Dataset Splits No The paper does not explicitly provide details on validation splits or methodology. It focuses on training and testing on a held-out portion.
Hardware Specification No The paper does not specify the hardware used for the experiments.
Software Dependencies No The paper mentions 'Adam optimizer [12]' but does not provide specific version numbers for software dependencies.
Experiment Setup Yes We set the latent dimensionality to 10. ... The variational program generates samples by transforming a K-dimensional standard normal input with a two-layer neural network, using rectified linear activation functions and a hidden size of twice the latent dimensionality. ... For f , we use a three-layer neural network with the same hidden size as the variational program and hyperbolic tangent activations where unit activations were bounded to have norm two. ... We used the Adam optimizer [12] with learning rates 2 10 4 for f and 2 10 5 for the variational approximation.
